These batteries, often labeled as 377 or SR626SW, are silver oxide batteries known for their longevity and stable voltage output. I appreciate how they can power my devices efficiently without frequent replacements.

Key Features to Consider

  1. Voltage and Capacity: Ag1 batteries typically have a nominal voltage of 1.55V. I always check the capacity (measured in mAh) to ensure it meets my device’s needs. A higher capacity means longer-lasting power, which I find incredibly convenient.
  1. Brand Reputation: I’ve learned that not all batteries are created equal. I prefer well-known brands like Energizer, Duracell, or Panasonic, as they tend to offer better performance and reliability.
  1. Expiration Date: One thing I always look for is the expiration date on the packaging. I aim to purchase batteries with a longer shelf life, as I want to avoid any surprises when I finally need to use them.
  1. Quantity: Depending on how often I use these batteries, buying in bulk can be more economical. I usually opt for multi-packs to ensure I have spares on hand when needed.

In my experience, Ag1 button cell batteries are relatively affordable, typically ranging from $1 to $5 per battery, depending on the brand and quantity. Buying in bulk can save me money in the long run, especially if I frequently use these batteries.

Tips for Safe Handling and Storage

  1. Keep Away from Children: I always ensure that my batteries are stored safely out of reach of children, as they can pose a choking hazard.
  1. Store in a Cool, Dry Place: I keep my batteries in a cool, dry environment to prolong their lifespan. I’ve noticed that extreme temperatures can affect battery performance.
  1. Proper Disposal: When my batteries are depleted, I make sure to dispose of them responsibly at designated recycling locations, as they contain materials that can be harmful to the environment.
